.To al! w71 om. 'may concern Be it known that 1, TILLIAM GARFIELD Summon. a citizen of the United States of .tmericau resident of London, England, have invented certain new and useful Improvements in Type-W'riting Machines, of which the following is a specification.

lily present invention relates especially to tally strip mechanism and its general ob- Iiect-is to provide improved mechanism of the character specified.. l f

More specifically one of the objects of my invention is to provide novel ribbon mechanism. that is especially adapted for tally strip work; another specific object is to provide improved tally strip feeding and controlling devices; another. object is to provide improvedpaper severing devices; and a still further object is to provide an improved platen construction involving' a plurality of platens or backings for the paper.

To the above and other ends my invention consists in the features of construction, com'- binations of devices and arrangements of parts hereinafter described and particularly pointed out in the claims.

The preferred form of my inventionis illustrated in the accompanying drawings,

1 and 2. Fig. 4 is a fragmentary vertical sectlonal view taken on a plane Indicated by the dotted line g/-y/ in Fig. 1 and looking in the direction of the arrow at said line. Fig. 5 is a fragmentary horizontalI sectional view taken on a plane indicated by the dotted line .2s-z in Fig. '1. Fig. `6 is a vertical sectional view taken longitudinallymnd centrally of the tally stripfroll holders. `Fig. 7 is a fragmental-y detail elevation partly in .section of the paper severing devices. Fig. 8 is a fragmentary vertical sectional view-taken transversely through the platen of a No. 10 Remington front-strike typewriting machine embodying myinvent'ion.l Figs. 9, 10, 11 and 12 are detail views of parts of the fibbon mechanism. Fig. 13 is a view corresponding to Fig. 10 but sl J'Wing the modified .construction.

As shown in Fig. 8, the top plate" 1 of the No. 1 0 Remington front-strike typewriting` vmachine 1s provided with opstanding lugsv 9. and?) to which are fixed oppositely grooved track-ways -t and coperating through anti-friction balls G with the grooved front and rear bars numbered respectively 7 and 8 of a truck which further comprises end bars 9. Said truck shiftably supports through devices including links or connecy tions 10 a platen frame which comprises end bars 11 and connecting cross bars 12 and 13. A rotary platen 1l whichhas an axle 15 is mounted on the platen frame which, together with the truck, constitutes a traveling. carriage. Operatively connected with the right-hand end of the platen is a line spacing ratchet wheel 16 (Fig. 1) with which cooperates a hand-controlled'pawl of ordinary construction (not shown). Associated with the platen 14 are paper controlling a'nd Afeeding devices comprising a detlector 17 which is supported Ion a rock shaft 18 bearing in the end bars 11. Protruding through suitable openings in the deflector are the sections 19 and Q0 respectively of the main and secondary feed or pressure ,being mounted on a rod or shaft 2G supported on the platen frame. The downwardly extending arms of the three-armed levers are connected to springs Q7 which normally maintain the pressure rollers in operative engagement with the platen, and the upwardlyextending arms of said levers are adapted to be engaged by fingers or lugs 2S fixed to the rock shaft Fixed to the left-hand end portion of said rock shaft is a release key or lever 29 (Fig. Q) and when this lever or key is pushed rearward the lugs 2S act on the three armed levers through their upstanding arms to,r overcome the springs 2T, swinging said levers on their axes and releasing the rollers 19 and 20.

In order to provide a suitable Amounting for the tally strip supporting devices the right-hand end portion of the rubber sheath 30 of thc,platen '1l is partly cut away as indicated at 312 forming a Wide'ehbllow.

annular depr'lsslon, and the remaining* portionfof the cath for the greater part of the width of this depression 31` is furtherv entirely cut away, exposing the core 32 of the,` platen 14 and forminga deeper and somewhat narrower depression 33 (Figs. 1,`

il, 3,5 and 8). Suitably secured to the core 2:12 oftheplaten 14 at the ends of the depresr sleeve 35 which is seated in the depresy f ion and engages at its end portions with what thinned do ,uidtrack-ways. It will be understood from wbstfollows' that Whenthe platen is rotated, the bands 34 will rotate Within thel end portions of the tube 35 but that at this time and at all'other times. said bands support said Said tube is formed at its ends with .ges 36 which provide bearings for the need end portions of rollers 37, the tube receiveV said rollers.` "lhesei rollers lare l the tube receivesa curved -washer'plate or covering 4G. which-mau be of the'v same iler piet extendafdinte aile. .as

Fixed. to the upper face or" the sleeve' asby riveting and 'projectingv upward through the washer 40 are short in )i'iglit posts 41,'the upper end portions whereof are threaded. `Received on these posts il is a convex plate or'bar 42 formed with openings to fit over the posts. (ln the posts or screw pins 4ll are circular metal. washers-43 interposed between said plate and the rubber washeror .plate 40. Sleeves 4l providedwith internal threads are screwed down on the threaded posts 41 and Vserve to clamp the plate 42 in place.

` Supported on the upper. ends of the sleeves lll) ,is a plate or bar 45 which is secured in place byheaded screws 46 which through 'openings in said plate 45 and are screwed into the upper ends ofthe sleeves 44. The plate 45 provides a supporte for the tally strip devices while the plate42 is a support for the tally stripribbon mechanisrn.

Said ribbon is adapted toco crate with the tally strip and is short in ength as comparedv ig. l2

with the main ribbon 'r indicated in which is controlled by the. usual vibratory mechanism of the Remington?. machine, this main ribbon being on'the freineof the machine or non-travelin .part as comprising ainutilated pinion 61 provided at its rear with'a seriesof crown gear 'teeth 62 are circularly arrangedA and exl'o tend around about half of the circumference of said pinion, said teeth being adapted to cooperate vin alternation with thepinions 5G. which bears in a bracket b4 secured by Screws 65 to the plate 42. Said plate, to; gether with the underlying washer plate 4() `may be cut out to provide space within which the pinion 61 may turn. Said .pinion is arranged at the rear end of the shaft (S2-3 which is horizontally disposed and extends fore and aft of they machine. Back of the pinion the shaft terminates in a rounded or coneelike head 6G and the pinion is conlined ixed'ly between said head and a collar 67 which Vis fast on the 'shaftGB and bears in a depression or seat 68 in the bracket 64.

The :forward end of the shaft G3 is reduced and threaded 'and receives a pair4 of interlocking nuts (Si) which'prevent accidental wthdrawal of thi shaft from its bearlng.

A s ,ring TU roiird around the shaft forward of t eroliar (3T urges said shaft rearward and maintains the rrmvn teeth (Sii normally in p0- sition to cooperate with the pinions. However, when one oi' the spool shafts 51 is pushed inward its ball end 53 will coperate with the conical head VG lo cani or force the sha-ft 63 forward against lthe spring 70, the gear teeth 6i? being thereby carried out of operative position so that they will no longer cooperate with the pinions 5G when the shaft' 63 is turned. The end of. the cone (S6 will cooperate with a groove formed back of ,the ball end to maintain the parts locked in the last described .relationship until the shaft 51 is pulled outward, permitting the restoration of the teeth G2 to operative po- The pinion G1 is also formed with a set of teeth 7l projecting forward oppositely ffom the. teeth 62, said teeth 71 providing acoi'nplcte crown gear wheel which intermeshes .with a pinion 72 secured to the inner end portion of a shaft 73 which eX- tends. through an opening 74 formed transversely in the right-handv sleeve 44. The

right-hand end 'portion of saidl shaft takes bearing in. the forward opening or hole in ther-beaiigplate 50. To give additional v Stability' to said shaft its inner end which is reduced in diameter and projects lel'tward beyond-the pinion 72 preferablv engages inv an openirfgv G4 formed in the bracket (34. Near its outer end said shaft 73 is provided with? a' ratchet Wheel 75 with which copera'tes a pawl 7 6 pivoted to a pin 7 7 extending laterally outward from a radial arm 78 pivoted looselymn the shaft 7?). A collar 75l is fix-ed to the shaft 73 to the left of the bearing plate 50 and a Washer or spacing sleeve 80 is arranged on said shaft to the right of said plate, said sleeve. being confined between the arm 78 and said spacing sleeve and said arsn 78in turn being` confined be,- tWeen said sleeve and the hub ofl'the ratchet The pinion 61 is fast on a shaft G3 wheel 75. The construction is such that endwise movement of the shaft 73 is prevented as well as displacement of the arm 78 lengthwise on said shaft. A link 81 pivoted at its forward end on the pin 77 and confined loosely between the arm 78 and the pawl 76 extends rearward and downward. and is pivotally connected near its rear end by a pin 82 ,with a'crank arm 83 fixed to the rock shaft 18 neariits right-hand end and extending upward therefrom. A plurality of holes 84 on said crank arm and a plurality of holes 85 in said link 81, which holes are adapted for the reception of the pin 82, afford variability in the connection be tween thecrank arm and link and conse quent change in the feed movement communicateil to the shaft 73 by its pawl and ratchet devices.

The construction is such that each time the release lever 29 is operated to release the pressure rollers 19 and 20` it'aets through the crank arm 83'and link 8l to automatically actuate the pawl and ratchet devices 76, `to turn themain ribbon driving shaft 73 and causes it to actuate the Sub-shaft 63, thereby turning the mutilatedwgear 62. The teeth constituting said mutilated gear are so arranged in respect to the pinions 56 Ithat they can only cooperate with lone of said pinions at a time and it will be understood that during each complete revolution of the mutilated gear 62 it will act. in alternation on said pinions. For slightly less than half of its-travel it will intermesh with one pinion 56 to turn the associate ribbon spool and Wind the ribbon thereon, the other spoolA being disconnected and permitting the ribbon to. unwind. Duringa corresponding period of the same revolution the gear 62 having been turned so as to. automatically disconnect it from the first pinion 56 will act on the other pinionv` automaticallyv reversing the. ribbon feed and winding the ribbon back Aon the opposite. spool. made for winding the auxiliary ribbon back and forth .from one of its spools tothe other for a comparativelyv short stretch or portion of its length, the ribbon feed being automaticallycommunicated by the feed roll release mechanism and the reversal of said feed being also automatically effected without attention froni the operator and independently of the ribbon itself. It will be umlorstood that the short stretch of ribbon thus used will become worn in time and in order to advance the ribbon to bring a fresh l'iortion of it into use, the operator has only to push in `against one of the buttons 54, causing an axial, inward, or sliding movement of the shfaft 51. This has the double effect, as will be clearly understood from Fig. 10, of connecting 'saidshaft with its spool and ofdisconnecting it from the driving gear 62, said driving-gear being moved forward to an inL effective position; `It isthen only neces- .sary to turn the button 54 to' feed the auxiliary ribbon 58 hand to an extent suiiicient to carry the used portion entirely out of theprinting field and to advance a fresh portion into osition, such that it can beautomatically fe back and forth between the spools over the printing point when the shaft 51 has been retracted or pulled outward to the normal position.A In this way,

provision is made for thoroughly yexhausttra ing', the auxiliary ribbon by employing comparatively short sections of it until these sections are successively exhausted.A The length-of these sections is governed to some transversely at right angles'so that Vit will be pvarallelwith and opposite to the print-- .ing linei' To this end guidinf devices are provided which, as appears rom Figs. 1 and 2, vcomprise a guide bar 86 which is ar` rangedlfonward of vthe plate 42 and is provided its ends with ears 87 that are curled around a'pivot rod 88 secured in a longitudinalopening in'said platef42. Be-

viding turning bars. In the present instance the ribbon spools are arranged near the ends' v:fondi said" ears the guide bar 86 has extensions/which curve downward overthe front face of the platen and terminate in diagonal or inwardly inclined slotted portions 89 proof the cut-out in the platen'and the ribbon is led 0H one of said spools and downward over the'turning barwhich is below the same, thence inward atright angles to its downward course and longitudinally of the platen .opposite the printing line thereon,

' thence over the other turning bar and upward to the ribbon spool which is above the Same.

vPre-ferably 4an auxiliary striking surface or platen is provided for backing up -the tally strip so that it may properly receive type impressions vthrough the auxiliary ribvbon 7. In the present instance this auxiliary low theprinting portion of the auxiliaryl ribbon and is Kprovided at its ends wit rearwardly turne ears 93 which are pivotally supported-on pins 94 that project laterally outward from the ends of the tube 35; A

wire spring 95 secured to ahg 96 on said bar 93 extends upward and backward through an 'opening 97 in said tube and engages/with the back of saidtubeandI tends f normally to maintain the auxiliary' platen -90 in contact with the sleeve 'just below thev front beveled edg'of the washer yplate :40 'with -which said platen section 90'form's-a continuous'surface to facilitate the smooth.l

This feeding is further xfacilitatedby" the rollers 37 carried by said sleeve.;` -A' leaf spring 98 securedto the bracket 64 by one f` the screws 65 acts on thebar 86 to maintain land even feedingl of the ribbon thereover.

the ribbon guide pressed down, with [the printing portion' of the ribbon-close to the" platen section while a detent spring 99 alsesecured in `place by said screw coperates with lthe pinion 72 to prevent accidental operation of the ribbon feeding mechanism.

The mounting of the -auxiliaryplaten enables itto be readily removed when worn and replaced by a new'lplaten section. -To

do this the bar 93 is swung'ou'tward on the pivots 24 against thepressure ofthe spring and the platen or anvil 90 is lifted out of the open slots inthe fingers 92. Then a new' 'platen strip is inserted andthespring 95 is allowed t'o -force it rearward into engagement with the face of the tube 35 and'under the edge of. the plate 40 which preventsv accidental detachment of said platenfstrip.'

The ribbon mechanism'inay be modified in various respects. An'illustration of the changes which may be made appears in Fig.

13 where an' auxiliary ribbon spool 58 xed r to a sleeve 55 providedwith a pinion 56 is shown supported on a shaft 51 which bears lconnect the shaft 51 with its spool 58 through the teeth 59, 57', the shaft 51 is rotated by hand instead of pushed in as in the prior construction. This rotation of the shaft causes the pin 104 to coperate with the spiral groove 103 to" cam or force the shaft inward longitudinally until the pinion is brought-into engagement'with the annular groove 102, said groove coperating with the pin 104 to maintain the shaft looked in its inmost position indicated in Fig. 13 at which time it will be operatively connected with its spool lso that subsequent rotation of said shaft will force the spool to turn with it.

The tally strip Y supporting and controlling devices are illustrated'in Figs. 1 to 6 and 8.- They are' mounted on the bar 45, which bar has'arearward extension 45 at its righthand end, which extension isat right angles.

to the body of the bar 45 'and terminates in sleeve Said extension may be given ini creased rigidity by a piece 45h suitably fixed to itsunder side. jAn angular bracket 105 is screwed or otherwise suitably secured to the left-hand endof the bar and extends up- 1'0 ward at right angles thereto, while near the `ri J;ht-ha1ul end of said bar is suitably fixed yan upright-arm 106. Fixedly secured to the arm .V106 near its top by a headed screw 107 is a hollow rod 108 terminating at its right' .15 hand end in a` circular head or .flange 109 which ahiits against the inner face of the arnr100. The rod 108 provides a support i for a. tally 'delivery spool comprising a hollow core or tube 11() which is closed at its 2'0 left end and at its right end is provided with aI circular flange 111 which may be grooved or cut out to lighten it. rVliey core 110 lits over the supporting rod 108 and bears rotatably thererih, being held against detachment g ,by a headed screw 112. Said screw is threaded into the outer end of the rod 108 which may be provided on its outer face with a boss which the end of the spool core is apertured to fit over and bear on. said end being loosely 39 confined lwtween-the head of the screw 112 and the rod 10H. A rod or Shaft 113 having reduced end portions which bear in the liu'acltet 105 and the arm 100 supports the tally receiving roll holder which is arranged below the delivery holder and comprises a hollow core 114 and disk-like flanges 115 and 110 which are apertured to bear rotatably on the rod 113. A wire detent spring 117' suitably Vsecured to the outer face of the 40 flange. 115 is adapted to engage in either of two grooves 11R and 119 formed circumferentially in the rod 113. thus allowing the roll` holder or spool to rotate in either of two predeterinined locations lengthwise ot' said rod.

' Fixed to the rod 1.13 to the right of the flange 116 is a disk 120 provided v.with a laterally projecting pin 121 which is adapted to engage 4 with anyone of a'plurality of A holes 122iormed in the spool flange. Y11G when the detent 117 is engaged with the groove 118. At such times the'spool is connected or clutched to the rod orshaft 1.13 so that rotary movements communicated to said rod will he transmitted to the spool.

However, by pulling the spool toward the left, the spring 11'( may be disengaged from the groove 118 and caused to engage with the groove 119, this movement disengaging the pin 121 from the hole 122 and disconnecting the spool from the rod so that the spool. may be rotated by hand independently of said rod. Thisis convenient when it is desired 'to u.. .vind the written portion of the `ta11y strip from the receiving spool or Afor otherwise controllingthe tally strip independently of regular line spacing, this being readily accomplished by turning the spool by one of its flanges. The tally strip, indi-` cated by p', is in .the present instance a narrow work sheet which iswound in roll form on a pasteboard core c which is slid on the core 110 of the delivery Spool and 'rictionally engages therewith. The free end of the tally, strip is led ott' from the/delivery roll downward overa guide bar 123 behind the undercut or recessed portion) 31 of the platen and thence upward at the front side ot' the -same over a guide bar 123a and to the rear of the receiving roll holder or spool to which spool it is suitably .secured as by a clamping bar'12-1 pivoted at 125 to the flange 115 and adapted to be' swung on its pivot by a tail piece 120. Said bar extends from its pivot through a slot-way 127 in the Hange 115 along the core 114 and is providedat intervals with pointed pins 128 which cooperate with holes 129 in the core 1.11 to elam`p the free end of the tally strip to the receiving roll holder. 1n the present instance the. tally strip is preferably of paper that is of an open texture or quite thin or tissue-like and is guided over or outside of the printing or horizontally disposed port-ion of the auxiliary ribbon r. the impressions whereof are consequently off-set on the back of' the tally strip and are read through the same. However, it preferred,

the relationship between the tally strip and its ribbon may be reversed. The main 'work sheet p is guided around the platen between the same and the main and secondary feed. rollers and its right-hand marginal rportion is superposcd ou and over-lies the tally strip, so that when its right-hand marginal por. tion receives type impressions through the` main ribbon r, such impressions will be duplicated on the tall'v strip from the auxiliary ribbon 1, they auxiliary platen providing a l'iai'flting lor the types when these duplicate impressions are'` made on the main and tally sheets. lt will be understood that when the platen is turned to advance work sheet a 'ecte d.

Line. spacing movements are communicated to the tally strip hy pawl and ratchet devices which are controlled by lthe ieed roll release lever 29. Said devicesraS appears from Figs. 1. 2` 4 and (i, comprise a ratchet wheel 120 which is suitably fixed to the shaft- 113 ytothe right of the. disk.120, and, if preferred, may be fixed to rsaid disk. detent spring 131 providedwith an ear 132 is secured by a screw 13? to the arm 10G and engages with the teeth of the ratchet 130 toi'irevent accidental turning of the tally receiving spool. oiiperative With the ratchet wheell 1510 is a, pawl 134. pivoted at 135 to alever 13G which in-turn is loosely pivoted `on the shaft 113 between the ratchet:l

. The pawl 134 carries a lleaf 'spring 137 which cooperates with a. laterallug or abutment 138 on the lever'136, said springftendinf constantly to maintain the pawlcengaged with the ratchet'wheel 130.- The'lever 136 is pivotally connected at 139 to a link 140 which at its l'rear end is formed with several holes 141 that are adapted to receive d pin, l screw or connecting .devicef142 that further is adaptedto engage with anyone of ,a plurality lof holes 143 formed in an upright crank arm 144. secured to the rock shaft 18, said pin 142 therebyv connecting -said link 140 with said crank arm.. The

construction is such that when the lever 29 is operated to release the main and second-- ary feed rollers as -to facilitate the removal of the completed main sheet ,fo and the insertion of a freshmain sheet, the desci'ibed connections comprising the crank arm 144, link 14,and lever 136 will operate on the pawl and ratchet devices. 134,

I tov turn the tally receiving spool to a predetermined extent and thereby to effect an advaiice-m0vement of theftally strip. During such operation the lever 136 turns 'about the axis of the shaft 113 as a center,

causing the pawl 134 to revolve bodily about said center. The advance of the tally strip takes place independently of both platens, the main platen not turning during such advance. It will b'e seen that means are provided for automatically line' spacing the tally strip and feeding the inking ribbon for-l the tally strip simultaneously with the throwing off. of the pressure rollers; that the tally strip is fed or drawn over a fixedA platen in one direction while the printing portion of the inking ribbon is fed in another direction at right angles to the di-,

rection of the lmovement ofthe tally strip; and that these feeding movements are accomplished by trains of devicesconnected with the feed roll release lever.

In order to maintain the tally strip in a comparatively' taut condition between its two roll holders,l braking devices are provided which are normally ineffective butl which are automatically caused .to operate on the tally delivery roll holder when'the tally line spacing devices are operated'. Said braking devices comprise, as shown in Figs.

4, Gand 8, a resilient metal strip or bandA 145 which is adapted to surround almost completely the periphery of the iangeglll of the delivery roll holder and'is` anchored,l at one end to a lug 146 projecting laterally "..opposite or free end of the band brake '145'y inward from the face of the head 109. The

isy connected by a coiled draw spring 14T with an upwardly extending .finger 14()a integral with the link 140. Normally the brake tends to swing away from the iiange iii-11 as show/p wheel 130 and the supporting. arm 106.*-

pivot v VFig. 4 but when therelease leven 29 is `actuated the resulting movement vof the link 14()l stretches ,thel

,spring 147, increasing its tension suliciently'v to cause it to draw Athe brake band into contact with the flange 111, the resulting frictionl being sufliiient to somewhat retard unwinding movements of the delivery spool and prevent overthrow. When the link vreturns to normal position the'inherent springof vthe brake band will cause it' to expand to the inoperative or Fig. 4 position.

which, as shownvin Figs. 1, 2,'5 and 7, coin- Tally strip severingvdevices are" provided-y prise a horizontal severing bar 148 pivotedv on a headed shoulder screw 149 which screws into the plate 45 t0 the right of the arm 106. 'lhe pivoted bar 148 is normally maintained in a forwardly extending position by a draw spring 150 which is` anchored at one end to a pin 151r on the extension 45al and 'at the other end hboks into a hole in the tail '148n of the bar 148. Thevaction of the draw spring 150 is limited by a'stop pin 152 projecting laterally from the bar 148 and adapted to contact with the outer face of the Aarm 106." The forward or free end of' confined between the heads of the screws 149.

and 155 and the bar 154 tend to press said bar downward, said springs being preferably arranged in depressions in 'the top of said bar. The downward movement of the bar at the right is limited by the severing bar 148 and at theleft by a washer 157 which surrounds the shank of the screw 155. Thel bar 154 isl thus spring mounted and normally provides with the bar .45 a slot-way or opening 158 throughfwhich the severing bar 148 swings, the construction enablingv the width of the slot-way 158 to be increased iro and providing that the bar or severing blade 148 shall always snugly t during the severing motion of the b de. The tally strip 7J passes upward in front of the. slot- .way 158 and is pressed against the front edges or -faces of the bar 154 and bar or plate v.45 -by the severing bar 148 when the latter is swung ltoward the -left and rearfward. The springs maintain a close yfit between saidbar and the slot-way 158 vduring this movement and the construction enables the tally strip to be cleanly severed so that the written portion maybe removed fr om the receiving Ispool and the new endportion then reconnected withsaid spool.
